"I've got prostate cancer, and I'm treating it with hemp oil, with cannabis," Chong said. "So [legalizing marijuana] means a lot more to me than just being able to smoke a joint without being arrested."

Chong first noticed symptoms eight years ago when he was jailed for selling drug paraphernalia. He said he started having prostate-related problems when he was drug-free for three years. "So I know it had nothing to do with cannabis," he said. "Cannabis is a cure."
